Troubleshooting
Unfortunately, working with external data is not always a smooth process. Many things can go wrong, including connection problems and a lack of temporary disk space.
Connection Problems
Difficulties with accessing external data can be caused by any of the following circumstances:
- The server on which the external data is stored is down.
- The user does not have rights to the directory in which the external data is stored.
- The user does not have rights to the external data source.
- The external data source was moved.
- The UNC path or network share name was modified.
- The connection string is incorrect.
- The installable ISAM driver has not been installed.
Temp Space
Access requires a significant amount of disk space to run complex queries on large tables. This disk space is required whether the tables are linked tables stored remotely in another format, or they reside on the local machine. The application behaves unpredictably if not enough disk space is available to run the query. It is therefore necessary to make sure that all users have enough disk space to meet the requirements of the queries that are run.
